Amamiya Hiroto is unlucky. His life consisted of misfortune after misfortune, culminating in an unlucky death during an incident on a school boat trip, trying to save a girl he barely knew. After death, he met a god of reincarnation who requested that the hundred or so dead passengers—one of them being the girl he tried in vain to save—be reincarnated into another world.... more>>

Yet a series of unfortunate events forced Hiroto to reincarnate with even less luck than before, starting with nothing but a tremendous amount of Mana. His second life, far worse than his first, came to a cruel end.

However, upon meeting the god a second time, he was informed that there would be yet another reincarnation—one that had already been set in motion and could not be stopped. Not wanting Hiroto to live long, the god cursed him before he was reborn in the hopes that he would either die quickly or commit su*cide.

Hiroto was reborn once more as a half-Vampire, half-Dark Elf. A Dhampir. Not wanting a fourth life, he is determined to live this third life with the only things remaining from his previous lives—death-attribute magic and his enormous Mana pool. <<less

A dungeon has appeared on the earth. It's a dungeon, like what everyone knows, a template dungeon. Suddenly, monsters appear in the dungeons that appear in various places, using a power that humans had never seen, like casting magic. The Earth, which has come to coexist with such dungeons, has been filled with unknown lifeforms, unknown technology, and skills created by the mana pollution caused by the appearance of dungeons.... more>>

That's good. No, it's not good.

The profession of adventurer was born, and each company bought the materials of demons that can be obtained and the items that can be obtained from the treasure chest for a large amount of money, and the world became an era of adventurers... That’s the templates, right?

...Well, it didn't happen. The reality is harsh, more than you think. Think carefully. The companies will buy large quantities of monster materials? Sure. But if it's just a sample for research, 100 bodies are more than enough, right? Yeah, that’s right. They didn’t keep buying. Therefore, there was no basis for an adventurer to be born. Of course, that means, anyone dives into the dungeon for no reward. Even if they have the skills, are they willing to risk their life? Of course, no.

Then, what do you think will happen? Fortunately, the weapons of the earth worked on the monsters. So, people were able to defeat them with a gun or missile. It's that easy.

...But they appear every day. I'm sure it's because they don't dive into the dungeon and thin out monsters on a regular basis. Well, if only a few dungeons appeared in the world, it was still good. But dungeons were everywhere. From dungeons with only weak monsters to dungeons with strong monsters.

The army fought with them every day. Using ammunition like hot water and shooting missiles like fireworks. Do you know what the result will be? I’m sure you know. In a situation where the dungeon is not profitable at all, it becomes a disaster, resources will go low and taxes will go high… Eventually, people abandoned all but the important cities. That sound like a disastrous situation, right? Well, in such a world, lawless zones are everywhere. And even if you want to do some trading, it’s not easy.

In such a world decades after that incident, I am still alive. And for the time being, I plan to save the world with the skill I have trained for decades. Secretly.

It's easy to save the world. I just need to use my skill "Equivalent Exchange Store". You see, it's in the corner, something like a vending machine. Hear me, it seems that 10 F-rank monster cores can be exchanged for 1 low-rank potion. <<less

A slightly twisted boy, who led a slightly twisted childhood, had enrolled to a slightly not so normal school.... more>>

Isolated from the general public, Toyoashihara Academy was a school that deviated from common sense as it was in possession of a dungeon underneath.

The strong were favored and the weak had their dignity trampled.

The dungeon, governed by game-like laws, was also affecting the real world…. <<less

One day, Saijō Haruto was forced by the Evil God of another world into reincarnation, and his soul was cursed.... more>>

He was reborn into a world of swords and magic.

In this world, one can become stronger by raising the level of their combat occupations.

Unfortunately, Haruto cannot raise his level because of the curse.

Haruto felt hopeless.

However, because of the Evil God’s miscalculation, Haruto obtained an inexhaustible supply of magical power.

This is the tale of how a Sage—cursed to have a “Locked” Status—managed to reach the pinnacle of strength by the effect of the curse. <<less

“Understanding” is “Stronger” than a Sword! There is no magic without any weapons!... more>>

But! This is the story of a man who wishes to live safely!

“So, I’ve come to a different world.”

That man stood alone in a mountain full of plants and creatures that he never knew nor saw before. He goes down the mountain by avoiding encounters with a big slime (and bandits), and is caught as a suspicious person in the castle he reaches. In interrogation the female knight Ilias met at the imprisoned place, when talking about the bandits seen in the mountain, Illias, who was stuck in the search for said bandits, hurriedly strikes the bandits . My wish to be a Hero, or to build a harem?

“I just want to live in a safe place” – a story that such a man survives the different world with “Understanding” as a weapon! <<less
